Where Security Research Meets Practice
Original research. Hands-on training. CTFs. A global security community built to test ideas, challenge assumptions and move cybersecurity forward.
Nullcon Berlin 2025 by the Numbers
ABOUT NULLCON
Built Around Research. Powered by the Community.
Nullcon began in 2010 with a simple idea: give serious security research and the people behind it a place to be seen, tested, challenged and shared.
Today, Nullcon brings together researchers, hackers, practitioners, builders, defenders and security leaders through technical conferences, hands-on training, CTFs, workshops and community programs.
From offensive security and AppSec to cloud, AI, hardware, OT, malware, product security and emerging attack surfaces, Nullcon creates space for work with technical depth, practical value and something meaningful to contribute.
Rooted in the open security community and built with an international outlook, Nullcon's vision is to bring this research-led community to more regions, countries and security ecosystems over time.

Community Voices
What Nullcon Feels Like From the Inside
“Serious research. Real conversations. No unnecessary noise.”
“What stands out about Nullcon is the technical depth. You hear research that is specific, practical and grounded in real problems, but you also get the chance to question it, challenge it and continue the conversation with the people behind the work.”
“The conversations between sessions are often just as valuable as the sessions themselves.”
“There is a strong sense of community here without losing the technical seriousness. Researchers, practitioners, hackers, students and security leaders can all be part of the same conversation, and that mix creates a very different kind of learning environment.”
“You come for the research, but the community is what makes you want to return.”
“There is an openness to Nullcon that is hard to replicate. People share what worked, what failed, what they are experimenting with and what they still do not have answers to. That honesty makes the conversations much more useful.”
